T0 all whom it may concern: I

Be it known that I, Gnoncn R. WATSON,

a citizen of the United States of America,

and a resident of Waterloo, Blackhawk County, Iowa, have inventedcertain new and useful Improvements in Speed-Finding Regulators, ofwhich the following is a specification.

My invention relates to improvements in speed-finding regulators, andthe object of my improvement is to supply for internal combustionengines or other prime motors or devices, means for regulating,governing, or controlling the fuel supply or other power producingmeans, including mechanism suitable for manual direction, in the findingor estimating the speed of the apparatus or of mechanism driven thereby.

This object I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Fig. l is a view partly in elevation and partly insection, with parts broken away of my speedfinding regulator asoperatively connected to the outlet-controlling valve of a carburetorsuch as is commonly used to supply gaseous fuel to an internalcombustion engine, not shown. Fig. 2is an end elevation of said devicewith parts broken away.

This speed finding device is particularly designed and appropriated foruse in combination with the fuel supplying means of an internalcombustion engine employed to operate a well drilling machine. Welldrilling machines of the larger sizes which are employed in drillingdeep oil or other wells cause their drilling devices to penetrate rockystrata of different densities and hard ness, requiring various changesof speed of operation in the reciprocation or lifting and dropping ofthe boring tool according to the different conditions. The operator mustbe ready to quickly change the speed of operation according to the need.This device, therefore, is devised to afford means for the operator toquickly and efi'ectively estimate from time to time a particular speedrequired in the operation of the boring tool and control the motorsuitably to change the speed.

In this instance, the device is operatively connected by means of aconnecting-rod 20 to a orank-arm 21 on the rock-shaft 22 ofthebutterfly-valve 23- within and controlling to an engine ofthe internalcombustion type which actuates the mechanism of the well drillingmachine.

The numeral 1 denotes a large channelbar upon which a spaced sector 2 isfixed by appropriate fastening means such as bolts,sa1d sector having abearing'openmg to receive a fixed shaft 3 on which an arm 4 is mountedto rock to and fro past and in contact with one face of the sector. Saidarm has on the opposite side of said shaft an integral bent finger 5,whose lower end has a coiled spring connection 7 to a projection 8 onthe bottom of the sector tending to yieldingly resiliently move said armto one limit along said sector. The numeral 9 denotes a screw passedthrough a threaded opening in the lower part of the sector to impinge atits end against a curved surface or edge 6 of the finger 5, and theother end of said screw is provided with a crank 10 for manual use. Thisscrew may be used in thrusting upon the finger 5 adjustably in placingsaid spring 7 under tension and in varying the position of the arm 4relative to the curved edge of said sector. This arm 4 thus serves as amanually adjustable stop or abutment for a hand-lever 14-13 which lattercontrols the connecting rod 20 and the valve 23. When the-lever 14-13 isin.

the position shown, the spring 7 is not under tension and the butterflyvalve 23 is closed. When it is desired to admit gaseous fuel to theengine, the lever 14--13 is swung'past the arm 4, and its outer part 14,after clearing said arm 4, which it can do because of the hingedconnection to 13 at the forks 18 and 19, pintle 16 and torsion-spring 17which tends to swing the part 14 toward the sector, may have its detent15 engaged overlappingly with the stop arm 4 to hold said valve more orless open.

An experienced operator can easily control this device using hisjudgment as to the proper speed for a change of condition in drilling,and can adjustably find and reg-- may be terminally connected pivotallydirectly to the part 13 of said hand lever, but as illustrated, it isconnected to a part 12 of another and slottedsector 11 which is fixed onthe same sleeve as thepart 13. This latter sector may be used inconnection with another connecting rod, when desired, to another part ofthe engine or the mechanism, but does not form a necessary element inthe invention.

The part 14 may be swung back on the pintle 16 while tensioning thespring 17 to disengage from the stop arm't when it is desired to closethe valve 23. v

After the adjustment of the stop-arm 4 with a desired rate of speedthereby induced in the operation of drilling, it often becomes necessaryto temporarily suspend the operation. Upon resuming, if the same rate ofspeed is to be maintained for a time, the already adjusted stop-armpermits this, without further efiorts at speed finding or loss of timedue thereto.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

In combination, a controllable regulating element, an adjustably mountedstop, means for adjusting the position of said stop, and a controlledresiliently jointed movable controller-device operatively connected tosaid regulating'element and adapted to be releasably engaged with saidstop to hold said regulating element in an adjusted position.
